Northern-blot analysis of the expression of the CPRD genes upon dehydration or rehydration. Total RNA was prepared from 8-d-old cowpea plants that had been dehydrated for 0, 1, 2, 4, 6, 8, 10, and 12 h or rehydrated for 0, 1, 2, 5, 10, and 24 h after dehydration for 10 h. Each lane was loaded with 10 μg of total RNA. The RNA was fractionated on a 1% (w/v) agarose gel, blotted onto a nylon membrane, and probed with ³²P-labeled cDNA inserts of the CPRD clones.
